The NOVA-3b dosimeter is a portable device for measuring γ-radiation equivalent dose and dose intake.


The dosimeter measures the radiation dose equivalent dose and the radiation intensity, date and time corresponding to the instantaneous measurement. The unit dose equivalent dose is μSv, the unit of intensity μSv/h.


Data stored in the dosimeter memory can be transferred to a computer using the BLUETOOTH interface. Data on the computer can be presented in the form of tables and graphs showing the total dose of registered γ radiation and the dose intensities of the user-selected time intervals. When data is transferred to a computer, each registered user information is automatically transferred to its data file. Through the computer, it is possible to change the recording time interval, device alarm levels for the γ radiation dose and dose rate.
